Neither he is coming on TV, or live in some shows or announcing publicly that he is investing nor he is making lucid statements about it.
All he would do is "conspiracy tweets". For example, yesterday's tweet "Doge Barking at the Moon". That's all guys and just after 22 hours it reached its ATH price and currently trading around it.
If he keeps doing 5-10 more tweets every other week then I don't know DOGE could be surfing around 1-2 dollars easily. This is crazy economy I have ever seen in my life.
Are you DOGE holder?
Elon Musk's influence is huge in the business world because Elon Musk is one of the CEOs and is destined to become the richest person in the world so many new investors have come to invest in cryptocurency due to his tweets and also his statements in various media. and I believe Dogecoin will continue to increase in the future.
